Hello, builders 👋
Welcome back to your weekly dose of AI Bytes. I keep coming back to one question this week: if a company can replace git in five months, what happens to the companies that sell software? 🌳 Anthropic built its own version control system, Scion, because its merges went from about 2,500 a day in May to over 30,000 in September.
Build is beating buy: Anthropic also built its own code review and code search in the same five months, one developer used Claude to make free alternatives to Word, Excel and PowerPoint, and Thorsten Ball is asking why we still open pull requests. Anthropic says most companies won't hit these limits soon. I don't think the software business is ending, but it has a new competitor: its own customers, building instead.

The AI notetaker that gets the hard words right
Your AI is only as good as what you feed it. Feed it a transcript with your product names, acronyms, and numbers spelled wrong, and you spend the afternoon hand-fixing the output.
Wispr Flow Notetaker uses your dictionary and calendar, so product names, acronyms, numbers, and uncommon names come out spelled right. It pops up when your meeting starts and captures Zoom, Google Meet, Teams, and Slack huddles with one click, no bot joining the call.
Then your meetings show up inside Claude or ChatGPT through the built-in connector. No copy paste. Try Notetaker free on Mac and Windows.
Thank you for reading. If you have any feedback, feel free to respond to this email. See you next week!
